[0035] As Figure 4 As shown, in an embodiment, the guide structure includes a first guide unit 5, which is disposed on one side of the air clamp fixed assembly 3 facing the circuit board 1. The first guide unit 5 is used to guide the positioning piece 2 into the air clamp gap 4. In this embodiment, the arrangement of the first guide unit 5 enables the positioning piece 2 (pin) to be guided more accurately when entering the air clamp gap 4, reducing positioning errors caused by misalignment, improving the positioning accuracy of the workpiece (circuit board 1 or PCB), and thus improving the accuracy of drilling and ensuring product quality.

[0036] In an embodiment, the first guiding unit 5 is a guiding groove (not shown in the figure), which is in communication with the air clamp gap 4, and the cross-sectional area of the guiding groove gradually increases from one end of the guiding groove close to the air clamp gap 4 to the other end of the guiding groove. In this embodiment, the guiding groove is designed to enable the positioning member 2 to be more accurately guided when entering the air clamp gap 4, thereby reducing positioning errors caused by misalignment and improving the positioning accuracy of the board to be processed (the circuit board 1).

During equipment maintenance and repair, if the first guiding unit 5 is worn or damaged, the guiding plate can be easily replaced or repaired without the need for large-scale adjustment of the entire guiding and positioning mechanism.

[0038] As shown in Figure 6As shown in the figure, in an embodiment, the first guide unit 5 is a guide groove 51, the guide groove 51 is in communication with the air clamp gap 4, and the cross-sectional area of the guide groove 51 gradually increases from one end of the guide groove 51 close to the air clamp gap 4 to the other end of the guide groove 51. In this embodiment, the guide groove 51 provides a clear path for the positioning member 2, ensuring that the positioning member 2 can accurately enter the air clamp gap 4 along the predetermined direction. At the same time, the extension direction of the guide groove 51 is consistent with the extension direction of the air clamp gap 4, so that the positioning member 2 will not deviate during the entering process, thereby significantly improving the positioning accuracy. The guiding effect of the guide groove 51 enables the positioning member 2 to quickly and accurately enter the air clamp gap 4, reducing repeated operations and downtime caused by inaccurate positioning, and significantly improving the speed and efficiency of automatic feeding, thereby improving the overall production efficiency.

[0039] As shown in the figure, Figure 6 As shown in the figure, in an embodiment, the first guide unit 5 includes a guide groove 51 and a connecting channel 52, the guide groove 51 is in communication with the air clamp gap 4 through the connecting channel 52, and the cross-sectional area of the guide groove 51 gradually increases from one end of the guide groove 51 close to the connecting channel 52 to the other end of the guide groove 51. In this embodiment, the cross-sectional area of the guide groove 51 gradually increases from one end close to the connecting channel 52 to the other end, forming a structure similar to a trumpet mouth, which can effectively guide the positioning member 2 to enter the connecting channel 52 and reduce positioning errors caused by inaccurate alignment. The connecting channel 52 is close to the air clamp gap 4 and its extension direction is consistent with that of the air clamp gap 4, ensuring that the positioning member 2 can accurately enter the air clamp gap 4 along the predetermined path, thereby significantly improving the positioning accuracy.

[0040] As shown in the figure, Figures 2-3 As shown in the figure, in an embodiment, one end of the positioning member 2 is connected with the circuit board 1, and the guide structure includes a second guide unit 6, the second guide unit 6 is arranged at the end of the positioning member 2 away from the circuit board 1, and the second guide unit 6 is used to guide the positioning member 2 to enter the air clamp gap 4. In this embodiment, the arrangement of the second guide unit 6 enables the positioning member 2 to be accurately guided during the entering process of the air clamp gap 4, reducing positioning errors caused by misalignment of the positioning member 2 and the air clamp gap 4, and improving the positioning accuracy of the to-be-processed plate. At the same time, the connection of the positioning member 2 and the second guide unit 6 makes the positioning member 2 more stable during movement, avoiding the problem of inaccurate positioning caused by shaking or deviation of the positioning member 2, and further improving the positioning accuracy.

[0041] In an embodiment, the second guiding unit 6 is fixed to the positioning member 2, or the second guiding unit 6 is integrally formed with the positioning member 2, and the cross-sectional area of the second guiding unit 6 gradually decreases from the end of the second guiding unit 6 close to the positioning member 2 to the other end of the second guiding unit 6. In this embodiment, the extending direction of the second guiding unit 6 is the same as the extending direction of the positioning member 2, and the cross-sectional area of the second guiding unit 6 gradually decreases, forming a structure similar to a cone. This design enables the positioning member 2 to more accurately align with the entrance of the air clamp gap 4 when the positioning member 2 enters the air clamp gap 4, reduces the positioning error caused by misalignment, and improves the positioning accuracy of the board to be processed.

[0042] In an embodiment, the number of the positioning member 2, the air clamp fixing assembly 3, and the guiding structure is at least two. The at least two positioning members 2 are arranged on the circuit board 1 along the first direction and are spaced apart from each other. Each guiding structure is used to guide a corresponding positioning member 2 to enter a corresponding air clamp gap 4. In this embodiment, the at least two positioning members 2 are arranged on the circuit board 1 along the first direction and are spaced apart from each other, and each positioning member 2 enters a corresponding air clamp gap 4 through a corresponding guiding structure. This enables the circuit board 1 to be stably clamped at multiple positions. Compared with the fixing mode of a single positioning member 2 and a single air clamp fixing assembly 3, the distribution of multiple positioning members 2 can more evenly disperse the external force received by the circuit board 1, effectively preventing the circuit board 1 from shaking or moving during drilling, thereby improving the stability and reliability of the fixing of the circuit board 1 and ensuring the accuracy and quality of the drilling operation. At the same time, the combined design of the multiple positioning members 2, the air clamp fixing assembly 3, and the guiding structure ensures that other components can continue to work even if one of the components fails or wears out, ensuring the basic fixing and positioning functions of the circuit board 1, reducing the risk of the entire production line stopping due to the failure of a single component, improving the stability and reliability of the production system, and reducing the loss caused by production interruption.

[0043] According to the guiding and positioning mechanism provided in the embodiments of the present application, the guiding structure can be arranged on the positioning member 2 (for example, a pin) and / or the air clamp fixing assembly 3. When the positioning member 2 starts to approach the air clamp gap 4, the guiding structure guides the positioning member 2 to move along the correct path through its specific shape or design, so that the positioning member 2 can accurately and quickly enter the air clamp gap 4, reducing the drilling error caused by deformation of the board or positioning deviation, effectively improving the accuracy and quality of drilling, thereby improving the overall product quality of the PCB, avoiding damage to the equipment caused by scratches on the processing table or deformation of the board by the positioning member 2, reducing the maintenance frequency of the equipment, and effectively prolonging the service life of the equipment.
